The ocean absorbs a significant portion of our carbon dioxide emissions, which is changing the chemistry of the ocean at an unprecedented rate. About one third of all emissions in the past 200 years have been absorbed by the ocean, causing an average pH decrease of ocean surface waters by about 0.1 unit – from 8.2 to 8.1. This change has already caused short-term, local impacts on ocean flora and fauna. The ultimate, long-term consequences of an increasingly acidic ocean may be unknown, but the potential risks are high. Ocean acidification is a growing problem as anthropogenic carbon dioxide emissions continue to change the atmosphere and climate. It is estimated that by the end of the century, there will be an additional drop of 0.2-0.3 units.
On our Ocean Acidification Initiative page you can learn about the work we are doing to research and understand OA in order to mitigate its effects. Here we have compiled some of the best resources on this topic.

Ocean acidification may benefit algae that are able to capitalise on increased carbon availability for photosynthesis but is expected to have adverse effects on calcified algae through dissolution. Shifts in dominance between primary producers will have knock-on effects on marine ecosystems and will likely vary regionally, depending on factors such as irradiance (light vs shade) and nutrient levels (oligotrophic vs eutrophic). The findings from this study strengthen evidence that brown algae can be expected to proliferate as the oceans acidify where physicochemical conditions, such as nutrient levels and light, permit.

In the Pacific-Arctic region, enhanced sea ice melt, respiration of organic matter, upwelling, and rivierine inputs have been shown to exacerbate ocean acidification. In addition, changing sea ice coverage is indirectly providing a positive feedback to OA as more open water allows for greater uptake of atmospheric carbon dioxide. These cumulative impacts also affect the carbonate mineral saturation states for aragonite, a proxy this study uses to define benchmark years when biological impacts are likely to result from reduced aragonite saturation states.

ACTIONS YOU CAN TAKE
Use our SeaGrass Grow Carbon Calculator to calculate your carbon emissions and donate to offset your impact! The calculator was developed by The Ocean Foundation to help an individual or organization calculate its annual CO2 emissions to, in turn, determine the amount of blue carbon necessary to offset them (acres of seagrass to be restored or the equivalent). The revenue from the blue carbon credit mechanism can be used to fund restoration efforts, which in turn generate more credits. Such programs allow for two wins: creation of a quantifiable cost to global systems of CO2-emitting activities and, second, restoration of seagrass meadows that form a critical component of coastal ecosystems and are in sore need of recovery.
